EASTHAMPTON - Police have identified the motorcyclist who was seriously injured Monday afternoon when he collided with a sports utility vehicle on Route 10 as 26-year-old city resident Timothy J. Woering.

Investigating officer Edward Murray said Woering was taken to Baystate Medical Center in Springfield with serious leg and head injuries.

A Baystate official said Tuesday night that Woering is in serious condition.

Murray said the accident occurred about 2 p.m. when Woering, riding north on Route 10, entered the southbound lane to pass a line of traffic, also heading north, that had stopped to allow the driver of the Volkswagen SUV to make a left-turn from a driveway at 203 Northampton St. into the southbound lane.

The motorcycle and the SUV collided in the southbound lane. “It appears that speed was definitely a factor, “Murray said.

The driver at the head of that line of traffic had stopped in order to make a right turn into the same driveway that the SUV was waiting to pull out of. The driveway in question can only accommodate one vehicle at time and so the driver seeking to pull in to the driveway had to first wait for the driver of the SUV to exit, Murray said.

The accident closed Route 10 from Lyman Street to Florence Road for more than three hours, police said.

Murray said the accident remains under investigation and that charges may be pending against Woering.

The crash was the region’s second serious accident involving a motorcycle on Monday.

In Granby, 28-year-old Abimael Mestre, of Ludlow, died of injuries in a 6:30 a.m. crash on New Ludlow Road.

The initial investigation indicated that Mestre was riding east near South Street. Mestre was pronounced dead at the scene and the crash remains under investigation.
